4:01 pm
>> good afternoon, i'm the chief building inspect err with the department of building inspection. today we are going to talk
4:02 pm
about green building, anwith me. he works closely to develop regulations and their implementation. in every case where there is a regulation or some other legislation, we have to consider, ok, how are we going to implement this? that is one of the biggest issues. developing an implementation plan and trying to communicate it to you, architects, engineers, designers, is one of our big challenges. we also want talk about some issues relating to green building's current and coming, and i think i have prepared a handout.
4:03 pm
we will start with a discussion of overall green building issues. most of san francisco is built with older existing buildings. we have some small number of new buildings every year. we have the california, and in august, 2009, it ratchets up a lot. we have standards for the
4:04 pm
ordinance. we do not have a whole lot of stuff that addresses 90% of the city's existing building stop. >> as for practicality in meeting safety standards, they are all necessary to address performance of existing building sites. >> barry, by the way, is running the new task force on what should we do about existing couldn't marshal -- commercial buildings, and how do we increase efficiency. >> energy first, but also water if this and say an overall resource deficience a --
4:05 pm
deficiency. major consideration. >> with commercial stuff, there is a big stuff to look up residential features, and those include a wide range of things, some of which are already covered. but if i can read through a list of handouts, what are the other laws that apply to existing new buildings, and what is covered, so you do not think it is just green buildings covering everything? so, for example, and this must be tangential, but regulations have been required in the building code since 1974. has to do with the quality of life and your environment. living in a quieter city as part of the overall concept of what makes our city a more habitable,
4:06 pm
hospitable place. i argue that that is a green building feature, as well. since 1974, we have a lot of stuff. energy and water conservation. these are already required to be provided at the time of sale of the building. it is very limited at the moment, energy and water conservation. you have to make sure you have a certain volume, 1.6. gallons per flsh. there is an interesting approach to green building, the historical approach, part of the state building code. and what the state says is that where it is a qualified historic
4:07 pm
building, more than 50 years old and with some historical value -- it does not have to be a resource, but it must be a landmark -- you may use the building code. in lieu of the regular california building code, in place of what they call the regular code. that allows you to do things to preserve the integrity of the building, and people say that saving the building is the greenest thing you can do because of the energy and materials. all sorts of opportunities, but it is not written as a green coat. but really, that is the fact a bit. >> yes, absolutely. of course there are limitations
4:08 pm
where transportation or other uses to be substantially changed. but in general, maintaining existing buildings is critical. >> and it has to do with building their ability. that is an issue. we are on to talk about this nationwide premier green building program of a product, many products that we use. it does not have too many points, but vulnerability is a topic that i think everyone to focus on. if you build a building that lasts for 100 years, it is a
4:09 pm
greener building and that designed without materials going 20 years and you have to take a new sign and window and replace the building. >> it is recognized in directly. there is credit in major systems for the shell or components if they are viable systems to retain, and particularly in residential standards, there are often points of durability, avoiding waste generated by durable systems instead of the shorter product. but you are right that there is a lot of room to extend that period -- to extend that. >> i think your ability will be one of the major issues.
4:10 pm
it is clearly a green building issue, intended to be rebuilt. it is a building whose time has come. hardly a green building. there's also a special about durability in terms of the materials to make it up. i am having a meeting next week with folks about the construction of buildings. right now, there is a requirement in the san francisco building code required to take your demolition construction debris to a registered facility, and they are required to do a recovery of some percentage. >> 65%, and you need a registered for any thing greater than a single axel picked up.
4:11 pm
>> of their committed to a recovery rate. we have recovery, but we're talking about deconstruction come up with the park that will be reused. -- the construction, -- deconstruction, with the part that will be reduced. so there is a regulation, and they put it in place, and that is all. especially with the green toad. san francisco's green building ordinance, and we both word about the -- wrote the ordnance and dealt with implementation with a small number of people, and it primarily relates to new buildings. i will go through the ordinance quickly and buried will help
4:12 pm
fill in the details. let's turn to table one. the table inside this ordinance. it focuses on two major topics. commercial buildings and residential buildings . so what are the requirements for a commercial building? we break them down into two major classes. mid-sized commercial, midsized is 5000 to 25,000 square feet. and we have another category here which is large commercial, over 25,000 square feet.
4:13 pm
ok. what about smaller buildings, less than 5000 square feet? are they covered? no. they are not. they are apt to be covered in the future in some way, but they are not. the midsized is for new mid-size buildings, and this is for new large commercial, over 25,000 square feet. all high-rises. not that big a building in san francisco for commercial. this applies to certain classifications. b, m are the two main classifications. b is a business. any kind of business occupancy. m is work.
4:14 pm
places where you sell things -- mercantile. there are places that are not covered. institutions, hospitals, and schools are not covered. certain types of assembly occupancies are not covered. i think that they might be covered. and part of the reason that these other elements are not covered is that this is a nation program, this development, and hospital standards are being developed, and laboratory standards for biotech are just now being developed. so policymakers in this group said, we do not want to adopt a requirement. so we have clear standards for b and m in place.
4:15 pm
for a mid rise commercial building, if you look at our table, you will see that we have an effective date, november 3, 2008, when all of these things went into effect. they tightened up in january 1 of 2009 and continued to increase until 2012, fitting the maximum requirements. the ordinance does not end on 2012, by the way. that is just the most stringent level. but you can see here is a rake and a requirement. you have to submit a checklist. tell us what leave it is. -- lead.
4:16 pm
>> it stands for leadership and environmental design. it sets of standards with the green council, a consensus membership organization of which the city is one of many members, and they maintain a set of standards under lead if recognizing other standards that are different areas of environmental performance. so if you document the project has met a given number of performance criteria, it can be a green building. so you get a third party verification, a credible verification that you have done something above and beyond the operation. >> so it has a certified standard, a silver standard, a
4:17 pm
gold standard, and people say they are building the building. that means they have met a standard for the green building council. it is the fastest-growing nonprofit organization. it is a proprietary system. if they own it, they sell it. by our product, certify our building. we in the city cannot say somebody has to purchase. you cannot say, you can only buy a chevrolet. we say in our ordinance, you need a standard or a checklist, and it has to be a lead check list or something similar. you are not allowed to say, you have to buy this product. so i really mean some equivalent
4:18 pm
standard. >> it is meaningful, so equivalent remains a hard by. >> isn't there also something in the planning code for seeing the leading goal? they were getting quicker service? >> they had a goal for quicker service doing green buildings, yes. if you are to submit a project that will achieve a gold rating, prior to 2012, if you were to submit it today, we would be prioritized to the top of the pile, in the building and the planning department and the department of public works. planning has raised the bar to what we had during a year or two ago. every single one seemed to want to be prioritized, so they were all leads.
4:19 pm
assuming we had a list of people waiting. so what the planning has done is raise the bar. plus another 20% of available points. so yes. but if you bring in a project today, with the building department, we will say you are at the front of the line, we will take you next. and the same other factors, water fish and landscaping, reduction, management, guidelines, the energy commission in. now, i want to skip the existing building stuff for a second and talk about residential building.
4:20 pm
make sure we're clear, it covers b m m. it does not cover smaller buildings yet. look at residential buildings, here. what residential buildings are covered by this or mets? -- ordinance? all residential new buildings, no exceptions. the first are small, four or fewer units. and then a the second step is midsize, and that is a building with five or more units, not a high-rise.
4:21 pm
a high-rise is a building which is 75 feet or more from lowest point of fire department access to the highest occupied floor. so a high-rise building has a different set of standards here for residential. when you have mixed occupancy buildings, residential, commercial, b and m, you get to choose which of the standards you want to use. because it is difficult to combine them. you get to choose your standards. for a small residential building, there is a requirement where if you look at our sheet here, in 2009 you must submit a check list, and there is a minimum of 25 green
4:22 pm
point's required. can you tell us what that means? >> sure. green points are points that you get for including prescriptive majors under the system, and for project to be recognized as green, it needs to meet at least a minimum standard, 50. , including a few prerequisites. energy requirements at least 15% better. so when the current standards past fort points, that is a measure that you need to include the checklist for drawings and also choose a few measures from the checklist that to be very easy to find. there is some recognition of benefits of development in terms of transit and other benefits. 25 points, and there is not a
4:23 pm
verification mechanism, because it is below the standard. it is a primary funding source. but they are likely to be a nonprofit consensus-based organization, helping with maintenance of standards overtime. >> so we have two standards. one is the lead standards promulgated by the building council, and the others paraded standards -- other is rated
4:24 pm
standards. the greens' standard started to focus initially, with leaves for homes and neighborhood development and all sorts. but still, green point rated is closest to what we would think of as a prescriptive check list of things a builder or developer might reasonably be able to incorporate into a small development without getting into the whole complex of analyzing the overall issues. we are trying to make it simple for the builder. >> in 2009, i got a product with the residents were your only requiring 25 points. the forms, 50.6, and there are a lot of different requirements.
4:25 pm
energy, 30, health, five, resource, 6, walker, nine,. is that being applied per, you know, 50%? how is that being done this year? >> this year, he simply need to show that you got 25 points. it is an educational point. people have to go through the checklist and see what you are doing, understand it. starting next year, in 2010, you have to be point -- and meet standards, and there is a minimum. >> any 25 will do this year, in other words, and next year the distribution categories to apply. >> i have heard that it is
4:26 pm
combining the standard or equivalent in the lead certification. >> great question. so the question was, there -- what is the relationship between lead for homes presidentially obverses green point rated -- presidentially, versus -- residentially? it is the primary standard recognized by the city for residential consideration, and there is a memorandum of understanding. lead is the leadership standard and lead for homes is a harder level to achieve.
4:27 pm
green point rated is designed to be credible but more friendly, so if you were just green -- you would not meet the minimum bar for lead homes, but if you were home certified, you could be simultaneously green point rated. does that answer your question? in most cases, for the sake of simplicity, that felt optional, to achieve multiple certifications. some credible standard that they're home has been built to some verification. but you could optional we choose to get certified, and there are other standards, as well. >> but if you hit lead, you certainly hit green point rating. it is builder friendly. it is a checklist, certainly. meeting the lead standard
4:28 pm
requires that your design team comes up with an overall strategy and be very integrated into the project as a whole. >> it is complex, especially for a single-family home development. it is certainly very doable. it is being done. but it is something that is focused for a project with sophisticated resources applied to it beyond what should be the baseline for construction. >> my second question is, is lead a nationally-certified, or is it more of a global recognition? is it also recognized in europe? do they have different standards? >> the answer is yes to all of the above. they encourage interested
4:29 pm
parties and other nations to develop their own organizations, and they could have their own standards. however, lead is still most recognized, and a home in san francisco. it is meaningful globally, but it is a u.s. standard. >> ok. so what do we have to do for these new residential buildings? it would be hard not to get 25 points.
